Effect testing experiment

Clinical tests were conducted using the Chinese medicinal composition obtained in claim 5 of the present invention, and commercial generation of 1-day-old broiler chickens from south-China-female-yellow-meat-chickens from Guangdong Zhiwei agricultural science and technology, Inc.

All the traditional Chinese medicines of echinacea, astragalus, wrinkled gianthyssop, elsholtzia, gypsum, dried orange peel, white atractylodes rhizome, liquorice and the like are purchased from Likantang pharmacy of Guangzhou city; tiangen fecal genome extraction kit, batch number: DP 328-021.

In the test, commercial generation fast large south yellow female dorkings of 1 day old are selected to be fed to 14 days old, 180-feather dorkings with healthy body and uniform body weight are selected and randomly divided into 4 groups, and each group has 45 feathers. Respectively setting as follows: a temperature-suitable group, a traditional Chinese medicine group and a heat stress group. The broiler chickens are raised on the net flatly, the artificial continuous illumination system is adopted, the chicken house is naturally ventilated, and the broiler chickens can eat and drink water freely. The chicken coop was cleaned and disinfected during the test according to the conventional procedure. The test period is 28 days, the basic daily ration fed by each group is the same, and the drinking water treatment and grouping conditions are shown in table 1.

Table 1 experimental design and grouping

6 chickens were randomly selected and killed in each group at 1d, 3d, 7d, 14d, and 28d of the experiment, and about 5g of the cecum content was taken and stored in a refrigerator at-20 ℃ for total DNA extraction and 16S rDNA sequencing. Extracting DNA of the cecal content bacteria by using a DNA extraction kit, detecting the extracted genome DNA by using 1% agarose gel electrophoresis, amplifying by using a 16s rDNA V3-V4 region after all the extracted genome DNA is qualified, sequencing by using an Illumina Miseq sequencer, and finally analyzing biological information.

SPSS19.0 statistical analysis software is used for analyzing the significance of the difference among the groups by single-factor variance, multiple comparison of mean values among the groups is carried out by Duncan's new complex pole difference test method, and the result is ' mean value plus or minus standard deviation '

Where sample n is 6. The histogram is made with GraphPad Prism 5.

As shown in FIGS. 1 to 4, it can be seen from the observed _ speces curves that when the sequencing depth is small, the number of OTUs changes dramatically, the number of OTUs increases greatly with the increase of the sequencing depth, and when the sequencing depth reaches 450000reads, the dilution curve still has an upward trend, indicating that new bacteria still exist in the chicken intestinal tract and are not discovered. When the sequencing depth reaches 50000reads, the Shannon curve reaches a saturation state, which shows that even if the sequencing concentration is increased, only the abundance of the species can be increased, but the diversity cannot be increased, namely the current sequencing amount is enough to carry out the microbial diversity analysis of the sample. FIG. 3 is a plot based on the chao1 index for predicting the total number of species in a microorganism, from which it can be seen that the sample curve is substantially flat, again demonstrating that the sample sequencing amount substantially reflects the abundance of the sample species. In addition, in order to test the abundance and uniformity of intestinal flora species in the sample. Sorting the OTU abundance of each sample, and then drawing a Rank-abundance graph of the relative abundance ratio of the OTU, as shown in FIG. 4, wherein the abundance distribution curve has a large fluctuation range at the beginning, but is in a flat state after the 1500 abundance value, which indicates that the overall trend of the species distribution in the sample is uniform.

As shown in fig. 5 and 6, in experiment 1d, the first principal component and the second principal component have contributions of 29.13%, 21.59%, 9.58% and 7.91% respectively based on weighted and unweighted principal coordinate analysis of UniFrac. As can be seen from the figure, the samples of each group have certain overlapping phenomena, which indicates that the individual difference between the groups is relatively large. As shown in fig. 7 and 8, in experiment 3d, PCoA in each group intersected, but some groups tended to cluster. In the weighted and unweighted coordinate analysis, the heat stress group starts clustering; clustering the two groups of traditional Chinese medicines in the weighted analysis; the difference in the temperature-adaptive group is larger. Indicating that environmental heat stress begins to have an effect on the intestinal flora. As shown in fig. 9 and 10, the clustering trend was evident for each group in trial 7 d. The hyperthermia group was separated from the other three groups in the weighted and unweighted coordinate analysis, and the heat stress group was more dispersed than the traditional Chinese medicine group and the traditional Chinese medicine group in the unweighted group. It is shown that in test 7d, the difference between the intestinal flora and the thermophilic group is caused by heat stress, and the individual difference in the heat stress group is larger than that in the other three groups. The heat stress factor is shown to lead the difference of intestinal flora, and the influence is larger than that of one group and two groups of traditional Chinese medicines. As shown in fig. 11 and 12, in experiment 14d, under the weighting condition, the intestinal flora adjusted by the traditional Chinese medicine starts to approach to the suitable temperature group, which indicates that the traditional Chinese medicine has good adjustment on the intestinal flora. If the weight is not weighted (only considering the species evolution relationship), under the condition that the second principal component and the third principal component respectively contribute 7.87% and 6.99%, the thermophilic group, the traditional Chinese medicine group and the two groups are completely separated from the heat stress group, the groups are respectively gathered in different areas, and the difference in the groups is reduced. As shown in fig. 13 and 14, in the test 28d, in the weighted coordinate analysis, the first coordinate and the third coordinate respectively contribute 9.90% and 33.43%, the thermophilic group is still far away from other groups, the distribution distance between the traditional Chinese medicine and the heat stress component is also obvious, and the two groups of traditional Chinese medicine are widely distributed and are close to both the group of traditional Chinese medicine and the thermophilic group of traditional Chinese medicine. In the unweighted analysis, the heat stress group is more obviously dispersed with the other three groups, and the traditional Chinese medicine group are closer to each other and are all close to the group with the proper temperature. The results show that the intestinal flora aberration caused by heat stress is more and more obvious through principal component analysis along with the increase of heat stress time, the intestinal flora of the heat stress group is obviously changed at 7 th after the heat stress starts compared with the thermophilic group, the difference in the heat stress group is larger than that of other three groups, the change of the heat stress flora caused by the addition of the traditional Chinese medicines tends to approach the thermophilic group, the effect is obvious at 14d and 28d, and the effect is more and more obvious along with the continuous medication of the heat stress.

As shown in tables 2-7 below, from the whole experimental stage, with the increase of broiler chickens, the abundance ratio of firmicutes is increased, and the long-term chronic heat stress can increase the abundance ratio of firmicutes. The abundance ratio of bacteroidetes is in a decreasing trend, and the abundance ratio of bacteroides can be reduced by long-term chronic heat stress; the addition of traditional Chinese medicines in drinking water can increase the bacteroidetes content to a certain degree, and one group of traditional Chinese medicines is superior to two groups of traditional Chinese medicines. In the test, the ratio of each group of proteobacteria fluctuates greatly, the ratio shows a trend of increasing and then reducing in time, the abundance ratio is relatively large in 7d, and the traditional Chinese medicine compound has a trend of increasing the proteobacteria. The traditional Chinese medicine can effectively regulate the reduction of bacteroides caused by heat stress. Heat stress reduces the abundance ratio of oscillatoria, while traditional Chinese medicines tend to increase. In a high-temperature environment, the clostridium is reduced, and the abundance ratio of the clostridium is increased after the traditional Chinese medicine compound is added.

The data in the same column are marked with different lower case letters to show significant difference (P <0.05), different upper case letters to show significant difference (P <0.01), and letters with the same or without letters to show no significant difference (P > 0.05).

TABLE 4 influence of Chinese herbs on abundance ratio (%) of chanterobacteria in chicken intestinal tract under heat stress

TABLE 5 ratio (%) change of abundance of Chinese herbs to Bacteroides under thermal stress

TABLE 6 abundance ratio (%) change of Chinese herbs to Oscillatoria under heat stress

TABLE 7 abundance ratio (%) change of Chinese herbs to delicate genus under heat stress

Clinical tests are carried out on the influence of the composition on the intestinal flora of the chickens under heat stress, and results show that the species abundance, the total species number and the diversity of the intestinal flora of the chickens are increased along with the increase of the age of the chickens in days. And the species abundance, the total species number and the diversity of the intestinal flora are increased due to long-term heat stress. From PCoA, the composition in the intestinal tract of the heat stress group is completely separated from the temperature-suitable group along with the increase of the heat stress time, and the addition of the traditional Chinese medicine tends to draw the temperature-suitable group close. The long-term heat stress can increase the abundance ratio of firmicutes and decrease the abundance ratio of bacteroidetes and proteobacteria, and the changes can be changed after the traditional Chinese medicine is used. The heat stress causes the reduction of the abundance ratio of the bacteroides, the clostridium flexneri and the oscillatoria, and can be relieved by the traditional Chinese medicine composition.
